Hi Iluv2cook:

The book you need is SPII.
Here's what it says:

Insulin-Sensitive w/ burned out glands:

You first need to be cleared by you physician before beginning or continuing your exercise program.

After clearance, you should do mostly flexibility/calmind and resistanc/adaptive exercises. Too much cardio raises adrenaline and cortisol lees, and you glads will burn out more.

If you are extremely exhausted and do not exercise, do not start and exercise program at this time. If you are extremely exhausted and are exercising, stop your exercise program at this time. After you have been eating well and resting for a minimum of one month, you may resume exercising again.

Start slowly with resistance and flexibility exercises first:
Flexibility: 15 to 30 min, 5-7 days/wk
Resistance: 30-60 min sessions 3 times/wk
Note: If you do not feel well enough to start or continue the above exercise program, try to incorporate 5 minutes of stretching in the morning and in the evening, and add in 5 min of walking twice/wk. This is a small but important start to get you ready to do resistance training again.

When you have partly healed your glands, add cardio to your program. start w/ 5-10 min sessins 2-3 times/wk at 65 to 75 % max heart rate on the days when you are not doing resistance training. Slowly build up to 20-25 min session 2-3 time / wk.

(Note: You will know when your glands are "partly healed" because you will begin to feel better and not worse).

While you are healing your metabolism, it is better to spread out your cardio to 3 times/wk. However, when you have completely healed, you may do 30-60 min of cardio 2 times/wk.
Alternate between cardio and resistance every other day - but do not exercise 7 days/wk.

Hope that helps you......
